We adopted concepts from survey items in the AAPPQ and the DDPPQ and included a separate concept of perceptions of training in substance use to develop a survey instrument specifically for chiropractors. Unpaid faculty in chiropractic practice external to a DCP-associated clinic with whom chiropractic students rotate with for community-based internships were not eligible for this study. A response from contacts at 16 out of 18 of the identified accredited DCPs (88.8% of DCPs) in the United States was secured. Reminder emails were sent to each DCP contact weekly with requests for the reminder emails to be forwarded to eligible participants at their respective DCP. Frequency of responses to each of the survey items was calculated on the Qualtrics platform.
